MOULD AND MILDEW

Mould and mildew are likely to be found in greenhouses when the weather has been abnor- mally hot and watering may have been exces- sive. Lack of ventilation promotes mildew, which can be counteracted by dusting or spray- ing with sulphur. Leaf mould on tomatoes, due to the same causes, is best attacked by burning infected leaves and spraying with one of the proprietory preparations sold for the purpose.
